You can configure an IPv4-only, IPv6-only, or a dual mode (IPv4 and IPv6) Grid, but the configuration example uses IPv4 addresses. In this example, you configure seven NIOS appliances in a Grid serving internal DHCP and DNS for an enterprise with the domain name corpxyz.com. There are four sites: HQ and three branch offices. A hub-and-spoke VPN tunnel system connects the sites, with HQ at the hub. The distribution and roles of the NIOS appliances at the four sites are as follows:
- HQ site (four appliances in two HA pairs):
- HA Grid Master – hidden primary DNS server
- HA member – secondary DNS server and DHCP server for HQ
- Site 1 (two appliances in an HA pair): HA member – secondary DNS server and DHCP server for Site 1
- Site 2(one appliance): single member – secondary DNS server and DHCP server for Site 2
Note: When adding an Infoblox appliance to an existing Grid, you must first check whether the Grid is running the minimum required software release of the appliance. For information, refer to the document, Minimum Required Release Software for Hardware Platforms, that was shipped with your product.
To create a Grid, you first create a Grid Master and then add members. The process involves these three steps:
- Configuring two appliances at HQ as the Grid Master. See Create the Grid Master.
- Logging in to the Grid Master and defining the members that you want to add to the Grid; that is, you configure Grid member settings on the Grid Master in anticipation of later joining those appliances to the Grid. See Define Members on the Grid Master.
- Logging in to the individual appliances and configuring them so that they can reach the Grid Master over the network and join the Grid. See Join Appliances to the Grid.
After creating the Grid and adding members, you use the Data Import Wizard to import DHCP and DNS data from legacy servers. See Import DHCP Data and Import DNS Data.
Finally, you transition DHCP and DNS service from the legacy servers to the Infoblox Grid members. See Enable DHCP and Switch Service to the Grid.

Cable the NIOS appliances to network switches. After cabling each appliance to a switch and connecting it to a power source, turn on the power. For information about installing and cabling the appliance, refer to the user guide or installation guide that ships with the product.
